' Application July 15,1943, Serial no. 494,806 1 Claim. ((172-128) Thisinvention relates to implements employed in the erection of masonry andconcrete structures andthe like, and more particularly to a combinedgravity-flow plasticcontainer and assov plement.

ciated spreader guide and s ge, broadly termed a trowel, in thespecification and clalm which maybe employed to spread ribbons ofmortar'on brick orblock courses. .a i H Animportant object of theinvention'is to pro vide such an implement, which supplies a ribbon ofplastic of a uniform thickness andwidth.

'Anotherimportant object is to provide a trowel or implement-of thiskind, which'supplies' a ribbon of plasticwith. the vertical sides of theribbon spaced a uniform distancefrom the planes of the virtical sides orfaces of the bricks, blocks or the li e.

Still another object is to provide a valved container for plastic (suchas mortar), and an associated channeled guide and gage carried by thecontainer and disposed below the valve, with a passageway to the guidewhen the valve is unseated.

- Another important object is to providea mortar spreader which willminimize waste'of the- Yet another object is to provide a valvedcontainer for mortarami anassociated guide and spreader, which may bewholly manipulated by one hand of the mason.

Still another object is to provide such an implement wherein theoperator will be aware at all kings of the quantity of plastic withinthe eon- Other objects and advantages of this invention will be apparentduring the course of the follow-- lug-detailed description of theinvention, taken in connection with the accompanying drawing, forming apart of this specification and in which drawingz, I

Figure 3 is a bottom planof the'novel trowel or implement. Figure 4 ianperspectiveview, showing rib.-

- bonsai mortar bein spread along the upper faces .of a course ofconcrete blocks, I I In the drawing, wherein for the purpose ofiilustration is, shown a preferred embodiment of the invention; andwherein similarreference char-.- acters designatef'corresponding partsthroughout' ll handle means l2 to move the implement along the course,and valve means l3, between the'con-r tainer or the reservoir l I andspreader and guide means ID.

As for the spreader and guide same comprises an inverted, elongated,channel shaped member it, having Opposite sidewalls I6 and H, the firstbeing termed the outer side wall and the latter the inner side wall. Theouter side means It, the

wall I8 is deeper than the side wall H, as shown particularly in Figure2,. and is provided with a substantially flat face l8, with the lowerportion of this face It adapted to slide along the upper portions of theside walls of conventional bricks and building blocks. The side wall IIhas a substantially fiat lower edge I 9, adapted to slide over a portionof the upper faces of these bricks or blocks. Anupper or top,horizontallydisposed substantially flat wall 20 Joins the wallsl6 and I1and is provided with an opening or passageway II, somewhat oval inshape, as shown in Figure 3, preferably disposed intermediate the endsof the member II. The member i6 is free of end walls,

'so that there is provided an elongated passage way 22 through themember ii, in communication with the passageway 2| and of an areagreater than the area of the passageway 2 I Preferably disposed directlyover the member II is the container-or reservoir l8, somewhatfunnel-shaped, as in Figures 1 and 2, having an open upper mouth 25,side walls 26 and end walls 21 with the walls converging downwardly tomeet the wall 2| at the passageway 2 I. The lowermost portions of theinner faces of these walls 26and 2lprovide a valve seat 28. 'Thereservoir i6 is preferably what the word implies-a container for .a'considerable supply of material, which may be drawn upon to supplymeasured volumes of material to 'the mean it, and is not, primarily, acontainer such as a conventional trowel for a small volume of material.Infant, in practice, it has been found feasible to provide a containerof a 12 quart capacity. The means Ill and II may be integral or'may beseparate parts joined together as by welding. Since some plastics, suchas mortar. are inclined toadhere to the walls of a container, a suitableon, as thin waste engine oil 29, may be applied to the walls 28 and 2.1.

, The handle means I2 is shown as comprising a; substantial straight,round rod Ill, bridging the mouth 25 of the reservoir it, having a head3| at one end and any suitable means, such as a pin 32 at the otherend,-with the rod 30 secured in suitable openings in a pair of ears 33extending upwardly above the 'mouth 25 from opposite sides upper end toprovide the twospaced-apart, semicircular handle-engaging portions 31and 38, shown in Figure 2, the extremity I! will have a tendency tospring toward the facing portion of the stem; When the portion 31 isabout the rod 30 (as shown in dot-and-dashes) the valve 35 is seated andwhen the portion 38 is about therod '30 (as shown in full lines inFigure 2) the valve is unseated, and plastic material may flow throughthe pafssagewayjl, until. the operator disengages the ortion 38 from therod 30, whereupon suction contact with the upper portion of one sideface 42 of the block 40. When the valve 35 is unseated, as by drawing upon the valve stem 36, the plastic B will flow through the passageway 2|and into the passageway 22- and fill it. Upon moving the implement alongthe course, guided by the elongated side wall IS in contact with thefaces 42 of the blocks 40, uniform ribbons 43 of mortar will be spreadalong the upper faces 4! of the blocks 40 ready to receive the nextcourse of blocks. It

will be noted that the ribbons 43 are so disposed.

that material will not be wasted, as by dropping into the hollows 44 of.the blocks 40, there is a neat, outer edge of mortar, uniform inthickness, and with this edge paralleling the vertical planes of theadjacent side faces 42 of the blocks, and all this is accomplishedrapidly, with the operator, looking down upon the work and container,able to ascertain at all times the volume of plastic B in theopen-mouthed reservoir.

Various changes may bemade to the form of the invention, herein shownand described, without departing from the spirit of the invention orscope of the following claim. 4

What is claimed is A- trowel adapted to form ribbons of mortar along theupper faces of bricks. blocks and the like, comprising a reservoir,having an open, up

. wardly-extending mouth and an exit at its lower end; a handle bridgingsaid mouth with the vertical longitudinal plane of said handlesubstancreated by the flowing plastic B will draw the valve 85 to aseated position and the portion I! will then engage the rod ll.

Operation of the novel implement is by hand. After the reservoir II issuitably coated as des"cri bed, arid the valve IQ is seated, a volume ofplasticB, as mortar, is poured into the reservoir l6. Whena course ofthe material C, such as hollow concrete building blocks is laid, theoporator lifts the implement, by the rod handle an tially bisecting saidreservoir, said handle being secured at adjacent its ends to saidreservoir; and a valve for said exit, having a stem extending upwardlythrough said reservoir to said handle and provided with means to suspendsaid stem from said handle at selected distances above saidfirstnamedpassageway, said last-named means including a resilientU-shaped arm having a pair of handle-engaging sections, shaped .toconform to and sets it upon the upper face 4'! of. asuitable block, withthe inner face I! of the elongated side l wall'l of. the spreader andguide means II, in

a portion of the transverse cross-section of said handle.
